VELOCIPEDE SEAT-POST.

No. 870,645.A

Specification of Letters Patent.

Patented Nov. 12, 1907.

Application filed March 18, 1907. Serial No. 362.963-

' To all whom it may concern:

tain` new and useful Improvements in Velocipede,

Seat-Posts; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a novel construction in a cushioned seat support for velocipedes, the object being to provide a device of this character by means of which `the seat is so elastically supported as to yprevent jarring the occupant in passing over rough roads or obstructions in road ways and consists in the features of construction and combinations of'parts hereinafter fully described and claimed.

ln the` accompanying drawings illustrating my invention Figure 1 is a side elevation of a seat support constructed in accordance with my invention. Fig. 2 is a vertical section of the same on -the line 2-.2 of Fig. l. Fig. 3 is a fragmentary detail top. plan view the seat being removed.

The seat post is constructed in the usual manner, the tubular member A of the frame receiving the tube B which latter isl split at C at its lower end and re- Y ceiving a tapered block D which is forced into the same to expand such tube B by means of the bolt E passing centrally through the said tube and at its threaded end entering the threaded central opening F of said: tapered block D. Secured to said post or tube B at its lupper end is the inclined arm G to which is secured a sleeve bifurcated at its free end as at I and in the bifurcated portion of which one end of the lever J v is lpivotally secured ina well-known manner.

- The said arm J is provided between its ends with a slot K through which the upper end portion ol' the seat post is adapted to pass as said arm is depressed, the latter being provided at its free end with a cylindrical shank Lto which the seat M is secured in any suitable manner. The said arm J is curved adjacent its pivotal connection withthe sleeve H passing below the latter and being then deflected upwardly so that at its middle portion it is normally supportedabove the upper end of said tube B and said arm Gr thereof. The said slot K extends partially into the curved portiontoreceive said arm G. Between yits ends said lever J is provided with projections N recessed at their free ends and which are adapted to receive the inverted V-sh'aped lugs O of a collar P disposed on said tube B and vertically movable on the latter. The said collar P is provided with a circumferential iange` Q against which the upper end of aI spiral spring R `surrounding said tube B is adapted to bear the latter at its `lower end resting upon the flange S of a similar collar T, vthe latter resting upon a split collar U secured to said tube B immediately above the upper end of the post A, said collar being clamped by means of a set screw V in the usual manner. The said spring R is normally maintained under partial compression and holds said lever at the upper limit ol' its movement. Upon receiving a load the said seat M will be depressed against the action of said spring R in an obvious manner and upon releasing the load said lever J will move into engagement with the arm G which forms a stop therefor. The said collar P is sulliciently loose on said tube B to enable it to becanted slightly as the direction of pressure thereon is Varied by the position of said arm J and said post constructed as above described is exceedingly comfortable and is very simple in construction and easily applied.

lI claim as my invention:

l. In a vclocipcdo. a sont post having a collar disposed on its lower ond. 4n spiral spring' supported thereon. n collar supported b v said spring' and movable on said sont post. a hifurcatcd arm on th(` upper end ol' said scatypost. a lover pivotnlly secured in thc treo end of said arm, said lcvorl being provided between its ends with a longitudinal slot adapted lo rcccivc said scalpost, and a sont mounted upon th(` lroo ond portion of said lover, the latter' being sul'ipori'od by said spring'.

12. ln a velocipede, a seat post having a collar disposed on its lower end, a spiral spring supported thereon, a collar supported by said spring and movable on said seat post, inverted V-shapcdlugs disposed on thc ripper face of said collar, a bifurcated arm on the upper end of said scat post, a lever pivotall)v secured in thc free end of said arm, said lever being; provided between its ends with a longitudinal slot adapted to receive said seal-post, and a sont mounted upon the froc cnd portion of said lever, and depending projections, on said lever disposed on each side of said slot und provided at their free ends with V shapcd recesses adapted to receive the free ends of said lugs on said last-named collar.

Il. In a velocipcde, a sont post having a collar disposed on its lower end` a spiral .spring supported thereon. a collar supported b v said spring and movable on said seat post, inverted V-shaped lugs disposed on the upper fnce of said collar, a liiiurcatcd arm on thc upper end of said seat post, n lever pivotally secured in the free end oi said arm, said lever being provided between its ends with a longitudinal slot adapted to receive said seat-post, und a seat mounted upon the i'roc ond portion of said lever, and depending` projections, on said lever disposed on each side ot' said slot and provided at their free ends with V-shaped recesses adapted to receive the lree ends of said lugs on said lasbnamed collar, said pivoted end portion of said lever being curved and extending below said arm of said seat post, and said slot extending` into said curved portion thereof.

ln testimony whereof, I `have signed my name in presence of two subscribing witnesses.

MEYER ROSEN.
